25Claims; (Cl. 131-37) The invention relates to: a. device for applyawrapper'to' the bunch ofa; cigarillo or a" cigar by 'means" of. arolling mechanism comprising a set ofroll'ers; into which"the-wrapper-ismanually fed."

Ifthe wrapper is; fedby"hand into therolling mechanism"thecigarmakeryapplies an adhesive paste "tofthet rear end or the ila'g'of" said wrapper with his fingers. In;thatcasetharear-end or the"flag; if any; ofthe wrapper meant for covering the head'i'of'f th*cigarillo or 'tl'ief cigar to" be made; is drawn acros'sfafihgerprovided with paste; This method has" several: disadvantages namely;the'ci'garmaker be skilled; he gets sticky fingers" andhc cannot preventthat" other parts of" the wrapper: than te nagare smeared withpaste:Moreover the rollingmechanism'has tobe stoppedmomentarilyinordertoenable the cigarm'aker" to" apply paste""to the useof" the wrapper.

The invention has. for its. object to provide meansovercoming'thesedisadvantages and conducive to a device, which makes itunnecessary to stop'the rolling mechanismfor the purpose of applyingpaste to the flag or thereap-end of the wrapper: Thus, the production ofthe rolling mechanismlcan b considerably:increased; The inventioncontemplatesthat infront of the location, where the' wrapper'is'" fedthrough the gap betweenitwo rollers of therrolling mechanismra guidingmember, for exampleaplate or. a roller, is provided extending .throughapart" of: the length' of said rollers attherend; .wher the ahead of thecigarillo or the cigar is made. It is still another object of theinvention to provide means for periodically applying paste to saidguiding member.

In this device the cigarmaker need only to press the flag or the rearend of the wrapper with his finger on said guiding member in order tohave the lower side of said flag or rear end pasted. Owing to therotation of the rollers of the rolling mechanism the Wrapper is drawnautomatically into the space surrounded by said rollers and the fla orrear end of the Wrapper is slid across the guiding plate or the guidingroller in contact therewith. It has been found that for making the headof the cigarillo or the cigar the rolling mechanism need not to bestopped, so that an increase of production of -20% can easily beobtained.

In order to avoid that the cigarmaker is hampered, when applying theflag or the rear end of the wrapper to the head of the bunch, by thepaste applying parts, the guiding member may be advantageously soconstructed that it is adapted to move'from and towards-the rollingmechanism. The means for applying paste to said guiding'member may becomeactive when said guiding member is removed from the rolling mechanism,so that they may be providedqat 'a place where they do not hamperthecigarmaker when controlling the'movement ofthe'rear-or flag end of thwrapper during thefeeding thereof to the rolling mechanism.

For detailed explanation of' the invention reference is made tothe'accompanyingdrawings, in which:

In the drawings there'areseen and designated by numerals I 2 3 andl'four rollers 'of a' known rolling mechanism by meansofwhich a binderleaf can be wound around a portion: of. scrap tobacco anda-wrapperrleafcanbe wound around the bunch thus obtained. Thebinderleafrand' the wrapper leaf" are introduced" into the rollingmechanism through a gap provided between: the rollers I and" 2- and" areseized by; the scrap" tobacco or'thebunch'; respectively;which''is"con"- tained in the space defined and surrounded by saidrollers I, 2, 3 and 4. Near the forward end of the mechanism constitutedby conical ends 5, 6, I, 8, 9, I 0 of the rollers, which ends are formedby solid cones or conically wound helical springs, a guiding plate ormember I l is provided which in one position is in front of the gapbetween the rollers I and 2 (Fig. 3). In that position said guidingplate II extends a relatively small distance from and near the end ofthe rolling mechanism, where the head of the cigarillo or the cigar isformed. It partly covers roller I and its conical end 5. If the wrapperis drawn into the rolling mechanism it is slid with its rear end or flagacross the guiding plate II in contact therewith. This plate I l issupported by an arm I2, which is secured to a rotatably mounted shaft I3carrying also arms l4 and I5. The arm or extension M abuts against thearm I6 of a two-armed lever, which is rotatably mounted about ahorizontal shaft I I journalled in a suitable bearing I'm. Th other arml8 of said lever is provided with a resilient wir applicator 19, whichmay be drawn into a container 2| containing an adhesive paste, by aspring 20 extending to and anchored on arm 18, said spring acting on thelever IS, It. Attached to the arm [5 is a driving-rod 22 driven by themotor (not shown) of the cigar-making machine. If the rod 22 is pulledto the left (according to the arrow), the guiding plate I is moved in adirection away from the rolling mechanism and the lever l6, l8 lifts theapplicator l9 out of the paste container 2| (Figs. 4 and 5).

The applicator I9 is made of thin wire metal and it is very flexible.When it is lifted (from its position I9), it droops a little, so thatthe guiding plate ll moving at the same time in a horizontal plane, istouched by said applicator. The latter slides then on the upper surfaceof said plate and thereby transfers a portion of the paste on saidplate.

If the guiding plate is in a position (Figs. 4 and 5) remote from therolling mechanism a binder leaf can be easily introduced in saidmechanism. If, on the other hand, the rod 22 is pushed to the right(according to the arrow), the guiding plate 1| returns to its position(Fig. 3) in front of the end portion of the rolling mechanism and thewire applicator i9 is again immersed in the tank 2! containing saidpaste. In that position of the guiding plate H a wrapper (not shown) canbe fed into the rolling mechanism. If the wrapper is drawn into therolling mechanism to such an extent that the rear end or the flagthereof has reached a position vertically above the guiding plate l l,the cigarmaker need only to press said end of the wrapper on the plateby means of one of his fingers in order to have applied the pastecarried by said plate to the lower side of the rear end or the flag ofthe wrapper. During the pasting operation the rolling mechanism need notto be stopped.

In the embodiment according to Fig. 2 the plate ll includes aguiding-roller 23. But for the inclusion of this roller the device is ofthesame construction as that according to Fig. 1 and operates in thesame way.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent is:

1. A device for applying a wrapper to the bunch of a cigarillo and likeproduct; comprising, in combination, a set of rollers constituting arolling mechanism having a forward end and into which said Wrapper is tobe fed, a member for receiving the flag of the wrapper, an arm adaptedto said member, and driving means adapted to cause reciprocation of saidarm and said member between a position at the forward end of therollers, where the head of the cigarillo or cigar is made, and aposition above the trough and in the path of the paste applyingapplicator, said driving means being also arranged to operative-1y coactwith said paste applying applicator.

2. A device for adhesively applying a wrapper to the bunch of acigarillo and like tobacco product; comprising a set of rollersincluding a forward'end and constituting a rolling mechanism for thecigarillo to which said wrapper is to be applied, a guiding member pastwhich the flag of said wrapper is fed to said rolling mechanism, an armarranged for swinging movement about a vertical axis and operativelycoacting with said guiding member, a reservoir for containing anadhesive, said reservoir being positioned adjacent said forward end ofsaid rolling mechanism, an applicator arranged for swinging movementabout a horizontal axis and adapted to dip into said reservoir and totransfer adhesive therefrom to said guiding member, and meansreciprocably moving said applicator about said horizontal axis and saidguiding member about said vertical axis in timed relation to each otherso that said applicator is swung out of said reservoir for transfer ofadhesive to said guiding member when the latter is moved from a positionadjacent said forward end of said rolling mechanism to a position abovesaid reservoir for cooperation with said applicator.
